LINT CLE ARING MEANS FOR DRAWING FRAMES AND THE LIKE Filed May 18, 19592 Sheets-Sheet 2 FIG 7 ""i llllliml v I INVENTOR M'l/iam E Lee BY a 1ATTORNEYS United States Patent 3,141,200 LINT CLEARING MEANS FOR DRAWINGFRAMES AND THE LIKE William Franklin Lee, P.0. Box 14, Glendale, S.C.Filed May 18, 1959, Ser. No. 813,918 12 Claims. (Cl. 19159) My inventionrelates to lint and dirt clearers or scavengers for textile machines andis applicable to all types of drawing frames, combers, coilers, cardingmachines and the like to prevent lint, dirt or foreign matter fromaccumulating in more or less sizeable bunches or masses and getting intothe sliver or other work.

For instance in the operation of a coiler, loose fibres separate fromthe slivers being operated upon and are floated onto such as marginalsurface areas of the flared trumpet entries, the trumpet-supporting beamor calender roll cover, and also onto the subjacent coiling mechanismcovers through which the slivers are directed from the trumpets.

Such fibres or fly with dust from the air and sometimes oil from machinesurfaces will, in the absence of preventive means, accumulate in varioussized bunches on the areas mentioned to ultimately topple into thetravelling slivers. Thus defective bunch-incorporating rovings andsimilarly defective yarns made from the latter result; and of course theyarn defects will also appear in subsequently produced cloth.

It is therefore the primary object of the present invention to overcomethe difliculty noted by the provision of simple, inexpensive, and highlyefficient means which can be readily applied by an ordinary mechanic tothe textile machines mentioned without material structural alterationthereof.

More specifically, the invention contemplates an air circulating meansfor the purpose specified, which will prevent loose fibres, etc., fromsettling on the surfaces mentioned and which can, for instance, bereadily applied to a coiling mechanism cover to be operated by theconventional coiler gear.

Invention also resides in certain novel features of construction,combination and arrangement of the various parts of the apparatusemployed, and in modes of operation thereof, as will be readilyunderstood and appreciated by those versed in the art upon reference tothe accompanying drawings in connection with the detailed descriptionthereof which follows.

In pursuance of patent statute requirements, the drawings illustratecertain now preferred examples of the invention. However, theillustration herein is to be taken as illustrative rather thanlimitative, since it is to be understood that my inventive concept issusceptible of other mechanical expressions within the spirit and scopeof the subject matter claimed hereinafter.

In the drawings, wherein the same reference characters have been used todesignate the same parts wherever they appear in the several views FIG.1 is an elevational view, partly broken and partly in section, of mylint clearer attachment applied to the coiler mechanism cover of aconventional drawing frame which is fragmentarily illustrated incross-section;

3,141,200 Patented July 21, 1964 FIG. 7 is a sectional view on the line7-7 of FIG. 6.

Referring to the drawings by reference characters and turning to theform of invention shown in FIGS. 1-5, inclusive, the invention isillustrated in connection with a conventional high speed drawing frame.

The fleece 11 is indicated as being passed from between two of the frontdrawing rolls 10 to a trumpet 12 from which it emerges as a condensedsliver 11a to pass between calender rolls 14.

From the calender rolls 14 the sliver 11a passes through the centralhole 15c of the coiler cover 15 to the usual coiling means which is notshown except for a fragment of the driven coiler gear 17. The coilingmeans delivers the sliver in coil form to the usual. coil-receiving can16.

The funnel-like trumpet 12 is conventionally mounted with its flaredmouth uppermost, as shown, in a hole in the calender roll covering beamor cover 13, as indicated in FIG. 1.

As indicated earlier herein, flying lint, dirt, etc., ac cumulates inbunches on the calender roll covering beam or member 13, the flaredtrumpet mouth and on the coiler cover 15 unless prevented from doing so,and such lint bunches topple or work into the sliver 11a to more or lessspoil same. Thus, ordinarily an attendant is kept pretty busy wipinglint accumulations from the surfaces mentioned. This is not only timeconsuming and thus expensive, but if the attendant is not careful, lintbunches will get into the sliver 11a which means that the yarnultimately made therefrom will be of inferior grade.

Coming now to my novel lint-clearing attachment, it will be seen thatsame comprises a gear case 18 composed of separably connected top andbottom plates 19, 20, respectively. These plates 19 and 20 have opposedinner surface recesses that define the shallow gear-receiving chamber21.

Gear chamber 21 has a frontal opening, as indicated, so that the chamberhoused spur gear 22 will have a portion projecting therethrough to meshwith coiler gear 17 when gear case 18 is assembled with the lowervertical flange portion 15a of coiler cover 15 opposite an opening 15btherein, as indicated in FIGS. 1 and 2.

As best indicated in FIG. 3, gear 22 is fast on the vertical shaft 23which is journalled in, and extends above, the upper end of theupstanding sleeve form bearing 24 that rises from top plate 19 and isfunctionally integral therewith. This shaft 23 carries the verticallyspaced air circulators, or impellers which are generally indicated at31, 32 and will be referred to in detail hereinafter. The impeller 31 islocated adjacent the top of the coiler cover 15 and the impeller 32adjacent and above the plane of the top surface of the trumpet-carryingcalender roll cover or beam 13.

In carrying out the invention according to FIGS. 1-5, the gearcase-providing plates 19 and 20 are secured together by two end bolts 26and a rear bolt 25. These bolts 26, 25 extend through opposedplate-provided apertures and receive nuts 26a, 25a, respectively.

Also to be noted is the fact that opposed end portions of plates 19 and20 have bolt aperture-surrounding cutouts which cooperate to define abearing seat 27 opening from the related gear case end. Each bearingseat 27 receives the inner bearing end 28a of an elongated attaching lug28 which bearing end is pivoted on the adjacent plate-securing end bolt26.

As will be understood, the attaching lugs 28 secure the gear case 18 tothe lower vertical flange 15a of the coiler cover 15. Thus lugs 28extend well beyond the adjacent gear case end as indicated in FIGS. 2and 3, and are apertured as at 29 to receive bolts 30. These bolts 30extend through the coiler cover flange 15a to engage interior nuts 30a,as shown.

Taking up now the details of the illustrated impellers 31 and Y32, anddealing first with the smaller lower impeller 31, it will be seen thatsame includes the relatively thick disk form base 33 having theupstanding concentric sleeve 34 which receives the gear driven shaft 23.Base 33 is vertically adjustable on shaft 23 and is secured in differentadjusted positions by a set screw 35.

The preferably leather-like or other flexible blades 38 are received inopposite outwardly opening base-provided slots 36 and are securedtherein by screws or pins 39. These pins 39 are received inbase-provided slot crossing holes 37 and, as shown, each blade 38 has ahole 38a through which the related pin 39 extends.

In the case of the upper or larger impeller 32, its mount is theelongated and preferably cylindrical member 40 which has opening fromits lower end the elongated concentric shaft (23) receiving bore 41.Bore 41, as shown, terminates short of the inner end of theblade-receiving cross slot 43 which opens from the upper end of mount40.

Exteriorly open and tapped transverse holes in mount 40 open into bore41 and cross slot 43, respectively, to receive the respective set screws42 and 46. Set screw 42, of course, secures mount 40 in variousvertically adjusted positions on shaft 23; and set screw 46 retains theimpeller blade 44 and its mount 40 assembled.

Impeller blade 44 is preferably of leather or other flexible materialhaving a material degree of stiffness, and it provides the enlarged endwings 45 as shown.

Referring now to the invention as expressed in FIGS. 6 and 7, the gearcase 5!) differs in certain respects from that indicated at 18 in FIGS.1 and 2 in that it provides thick and elongated bottom plate 51 and asmaller top plate 54.

Also the bottom plate 51 provides the open sided chamber 52 for gear 53that is fast on the shaft which latter projects up through top platehole 54a and the upstanding and functionally integral top plate carriedbearing 56.

Gear 53 and shaft 55, of course, correspond to elements 22 and 23,respectively, in FIGS. 1 and 2; and shaft 55 carries the impellers 31and 32 as in FIGS. 1 and 2, the description of which is by referencemade a part of this description of the FIG. 6 and 7 modification.

Bolt and nut assemblies 57 secure the gear casing-providing plates 51,54 together as indicated, but do not mount attaching lugs such as 28,28a in FIGS. 1 and 2.

The coiler cover 58 of FIG. 6 is the same as shown at 15 in FIG. 1except that its lower vertical flange portion 58a (which has cut out581)) is provided with the horizontal outwardly projecting posts 59adjacent opposite ends of flange cutout 5812. As indicated in FIG. 6,these coiler cover flange-carried posts 59 have the transverselyextending holes 59a adjacent their outer ends to receive the shanks ofscrews 61, having wing nuts 61a. The head-adjacent portions of thescrews 61 project transversely through holes in the fixedly carriedupstanding posts 60 of the lower gear casing plate 51. Thus posts 59, 60and wing nut-carried screws 61 function to hold gear case 50 and coilercover 58 assembled with the gear 53 in mesh with the coiler gear 17 asin FIGS. 1 and 2.

For purposes of this specification the coiler cover 15 (of FIG. 1) and58 of FIGS. 7 and 8 are to be considered as portions provided by thefragmentarily illustrated drawing frame of the art machine (see FIG. 1particularly).

The operation of both forms of the invention will be evident. The coilergear 17 acting through gear 22 (FIG. 1) or gear 53 of FIG. 7 drives theimpeller-carrying shaft and the impellers 31, 32 set up a circulation ofair in the region of coiler cover 15 (or 58) and trumpet 12. Thisprevents lint accumulations on or near said surfaces and the use offlexible impeller blades 38, 45 is preferable to avoid possible injuryto attendants.
